我想在我的应用引擎应用程序中运行 Maven。但是，我得到了这个例外：

从存储库 [本地 (C:\Users\user.m2\repository)、中央 (http://repo.maven.apache. org/maven2)]: 在任何插件库中都找不到插件

那是我的 Maven 文件：

我应该添加什么让它运行？

更新

我正在使用这个 Maven 插件，因为我得到：

项目的输出目录应设置为 /test/war/WEB-INF/classes

更新 2

    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>gwt-maven-plugin</artifactId>
        <version>2.5.1</version>
        <configuration>
            <webappDirectory>/test/war/WEB-INF/classes</webappDirectory>
        </configuration>
    </plugin>

我的例外是一样的：

项目的输出目录应设置为 /test/war/WEB-INF/classes

您还没有提到插件的组 id 或工件 id，并且 maven 正在尝试使用 groupid。

    <plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>gwt-maven-plugin</artifactId>
      <version>2.5.1</version>
    </plugin>

参考

  1. 您可以在中央 maven repo找到 gwt-maven-plugin 。
  2. 关于如何使用gwt-maven-plugin 的参考。
  3. 浏览GWT+GAE 应用程序的 Google 团队 pom 示例。

注意 - 我在一个示例项目中测试了你的 pom.xml，没有发现任何错误。
